Abstract
In order to provide a more efficient method and system for data lookups, it is proposed to provide the known CAM ( ) with an additional comparator ( ). The comparator ( ) does not comprise a memory circuit and therefore allows a faster comparison of input data (D to D ) with compare data (C to C ) than the known compare circuit ( ). In addition, it is proposed to temporarily inhibit forwarding of the output signal of the specific CAM circuit into which the input data (D to D ) are written, in order to avoid forwarding of a wrong match signal to the data processing system.
